Systematically investigate failing or slow traces in a Phoenix project. Use when the user asks why a span errored, why latency is high, why a tool call produced the wrong result, or any variant of "what went wrong" / "where do I look" inside a project's traces. Walks through narrowing with set_time_range and set_spans_filter, then inspecting span attributes for the failure signature.
This skill does not declare a tool allowlist. The agent host applies whatever default tools are available at runtime.
